Letters Patent N 106,765, dated August 30, 1870.

IMPROVEMENT =IN COMBINED HARROW AND ROLLER.

The Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom it may-concern Be it known that I, TIMOTHY BAILEY, ot'Wyoming, in the county of Stark and in the State ot' Illinois, haveinvented a Combined Corn-Harrow and Roller; and do hereby declare thatthe following is a lull, clear, and exact description thereof, referenceheilig had to the annexed drawing making a part of this specitication,in. which like letters Ot' reference refer to like parts, and in which-Figure l represents a perspective view;

Figure 2, a plan or superficial view;

, Figure 3, a sectional elevation from front to rear; and

Figure 4, one of the adjustable rear teeth.

This combined barrow and roller is designed, in the cultivation of corn,tO do the work Ot' harrowing and pulvcrizing the soil, at the same timethat followingteeth throw the pulverized soil around the tender plant,the teeth in question being madeadjustable for that purpose, and.running on each side ofthe corn-row.

In the drawing- A B O I) represent the frame of the harrow, the frontbar A and the side bars B C being of nea-rl y equal length, say fromfiveto seven feet long, the shorter bar, I), being in the rear of theframe, but parallel with the front bar.

Each ofthe side bars carries the usual forni of harrow-tecth, andconverge to the rear bar.

l` he front bar, A, is armed with two, three, or more adjustable teeth,whichl run immediately in front of roller G.

. Dvrepresents the rear bar of the frame, secured to the side bars, andcarryingT at either end a vertical standard, d, designed tor the supportand adjustment ot the handles E E, and two or more teeth e e, the bladesof which would exhibit a lozenge-shaped section, designed to move thesoil to either side of their course, according to the inclination givento tht-rny by a connnon form Ot' adjustment; as, for iustance, a threadcut ou their upper ends, which re spectivcly are. set in a vert-icalslot, h, cut in the bar, and secured on the surface of the lat-ter bymeans ot' a nut, each tooth Or blade having a proper shoulder of bolts,nuts, and several holes, or some equivalent fastening, to the standard.

F is the doublet-ree, for the draft, hinged or attached, at either end,to the front bar A.

G is a roller, not too heavy, about eighteen to twenty inches indiameter, and from eighteen to twenty-tour inches in length, placed inthe space in the. middle ofthe frame, and hinged to the front bar of thesame by a rod, g, on either end of its axle, the whole designed to allowthe roller free latitude on uneven soil.

'Ihe operation of this combined barrow and roller is as follows:

`Wheri the corn is germinating, or is an inch or tivo above the soil,the barrow and roller are used togetber, and I will describe thisoperation first.

The harrow and roller are drawn over the cornrows, the center of the,barrow and roller coinciding with that of the row. The teeth a. a a, inthe front bar A break the crust, or clods, and root out weeds on eitherside of the plant-s. The roller following breaks the olods left by theteeth, and pulverizes the soil around the corn.Y lhe roller is followedup by the adjustable teeth c e, in the rear bar D, one of which passeson either side ot the plant, and are set at such an angle by their nutsas will cause them to move the freshly pnlverized soil toward the corn,in a greater or lesser degree, as may be desired.

When the plants are too high to allow of the passage over them of theharrow and roller combined, the roller is removed from the harrow aswell as the front teeth of the latter', and cultivation is then done bymeans of the teeth in the side bars B C, and the adjustable teeth e e,in the rear bar ofthe harrow.

I claim as my inventionlhe arrangement of roller G and harrow A B C D,the former moving within the lat-ter, in combination with thebreaking-teeth, a a a, of the harrow, and the distributingteeth e e ot'the saine, the standards "d d, adjustable handles E E, and stationarydoubletree F, all substantially as and for the purposes described.

In testimony that I claim the foregoing, I, TIMOTHY BAILEY, havehereunto set my hand this 18th day ot April, 1870.

TIMOTHY BAILEY.
